"Miss Sparkles".

First real test run of a glass version of the Spartan. Setting it up to race in our EB mono class.
Neu 1521/1.5D, Turnigy 180A ESC, CNC 4514 prop. 6s lipo.

That looks really good !

Thanks Todd.
She sits pretty well for its first big test run. A bit wet in the corners. But we'll get that sorted.

Very impressive! Nice driving too!

[srislash]

Very nice, I love the sparkles!!

[785boats]

Thanks guys.
Race water will be a different prospect though.

[grsboats]

Very consistent..don't think its wet in the corners...congrats Gill

Could be perfect in race water

Hi 785boats

looks great. could you post a link to the eBay source?

I hope you are right Todd. The deeper V might cut through the chop better than the shallower V hulls.

zooma.
Here ya go.

Thanks Gill.
It just seems to drop the nose a bit & slow down in the turns.
I have a 160mm rudder blade on it that has had 25mm cut off it. I think I might take another 6mm off it for the next run.

Nice and smooth which is a first i've seen for a spartan... how do you waterproof your hatch ?

Hi there, Newbie here. How do i compute Ampere requirement of a motor for esc matching? Does it also mean that between a 4s and a 6s it would better to use a 6s pack since
it will lower the ampere load?

Hi Dimitry.
I made a 1/16" ply sub hatch which is simply taped down under the main hatch. The slot where the tongue of the main hatch goes in is covered with a strip of tape. A small slit is made in it & the tongue is forced through it. That makes a sort of a gasket all around the tongue.
At the moment the main hatch is held on with some tape across the back but I am going to fit some mechanical hatch locks to get rid of the tape.
Here's a pic of the sub hatch.

Most motors have a "Max Amps" rating in their specs. I generally use an ESC of twice that rating or a Seaking 180A ESC, which ever comes first. Nearly all my boats have the Seaking or Turnigy 180A ESC.

If the same size prop is used for both 4s & 6s, the 6s set up will draw more current because of the higher load on the prop due to the higher revs.
So a smaller prop is used on the 6s than on the 4s.
For example:
I race a 36" mono with a 1600kv motor in both our 4s class & 6s class. The only thing I change is the prop. A 452/3 blade for 4s & a 447/3 blade for 6s.
The total current draw is pretty much the same because both packs have about 25% - 30% left in them after a race.
I hope to be able to do something similar with this boat too.
